PAPER HOLDER FOB ADDING MACHINES.

Application filed September 13, 1923, Serial No. 662,456.

To alt whom it may concern.-

Be it known that 1, Nelson WHITE, a citizen of the United States, andresiding in Ithaca, Tompkins County, State of New 6 York, have inventedan Improvement in Paper Holders for Adding Machines, of which thefollowing is a specification.

This invention relates to adding machines, and has particular referenceto a carriage and paper roll holder therefor, and contemplates certainimprovements to the carriage disclosed in Patent 1,386,021 dated August2, 1921, Heber C. Peters. 1

While the device shown and described in the above mentioned patent hasbeen found satisfactory in use, the specific mountingl of the rollholder has been found more or ess inconvenient since it is necessary tomove the roll holder in case a wide paper is de- 2 sired to be used.

It is therefore one object'of'the present in vention to provideroll-flioldin'g means-as sociated with the carriage whereby rolls ofvarying widths may be employed, as desired.

A further object of the invention is to provide an improved means formounting the roll holder supporting arms.

Another object of this invention is the provision of adjustable ears forguiding the sides of the paper roll.

Other objects and advantages of this invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings which illustrate the preferred embodiment of theinvention andin which:

Figure 1 is a front elevation of the adding machine carriage and itsassociated roll holder;

Figure 2 is a rear elevation of the adding machine carriage and itsassociated roll holder;

Figure 3 is a right side elevation of the carriage; I 45 Figure 4 is aleft side elevation of the carriage; 1

Figure 5 is a fragmentary view of the paper release bar and itsassociated ears for guiding the sides of the paper from the roll;

Figure 7, is a sectional view through the I carriage Figure 8 is asection on the line 88 of I Figure 7 Figure 9 is an elevation of theelements of the roll supporting means in disassembled position, and

Figure 10 is a sectional view on its spindle.

Referring now more particularly to. the drawings, the carriage formingthe subject matter of this invention is provided with a mam supportingcasting 1, having a depending 011,101! 2 which supports a stud 3 on wineis loosely mounted a roll 4, said casting also supportin a second stud 5on which of the" roll,

is loosely mounte the roll 6, said rollers 4 and 6 forming bearings fora shaft 7 with whlch they contact, the shaft 7 being positioned in therear of an adding machine as 10 or the like, said second castin beingdesignated as 11 and as shown. clear yin Figure 7 is positioned justabove and parallel to the casting 1. Secured to each end of the casting11 by means of screws 13 or the like is customary. The upper face of thecastare side platesI-l, two in number, thus forming the carriage. Toprevent accidental separation of the castings 1 and 11, and to maintalnsaid castings in assembled position, re

tainers 15 are provided which are secured to casting 1 and extendupwardly adjacent th outer face of casting 11, the upper ends saidretainers being 'bent over, forming flanges 16 which overlap the upperedge of casting 11, the ends thereof extending within the planeo-ftheedges of the side plates 14, said extended ends forming limitingstops for the carriage in its movement, as will be hereinafterdescribed. a

A platen shaft 17, supporting a platen 18 isloosely mounted in the sideplates 1%, the platen being capable of rotation through the usualtwirlers 19.

Pinned to a shaft 20 which is loosely mounted in side plates 14 is anarm 21, which arm provides a carriage look through the medium of a pin22 which is so mounted in arm 21 as to engage within recesses 23 incasting 1 (see Fig. 2) or which may be withdrawn by means of a knob 24whereby the carriage may be frictionally locked instead of positivelylocked by the pin engaging in the recesses. The shaft 20 has pinned toone end thereof an arm 25, carrying a finger piece 26, which arm isnormally held in arearward position by a spring 27, one end of saidspring being attached to the arm 25 and the other to the carriage sideplate 14 by a pin 27. It will be obvious that by rocking the armforwardly the arm 21 will be lifted, thus lifting pin 22 out of a recessin the spacing bar from which position the casting 11 and its associatedadjuncts can be moved laterally with relation to casting 1, thismovement providing a columnar spacing for the paper.

Pinned to the platen shaft 17 adjacent one 'of the twirlers 19 is aratchet 28, the teeth of which are engaged by the detent' roll 29mounted on detent lever 30; lever 30 being pivoted at 31 to one of theside plates 14. The lever 30 is normally held in the position shown inFigure 4 by a spring 32 which has one end connected to the lever and theother end connected to the side plate 14 at 32. Pivotally secured to oneend of the before mentioned shaft 7 is a feed lever 33 and from theother end of shaft 17 depends an arm 34. Shafts 35 and 36 are rigidlymounted between arm 34 and the lower end of feed lever 33. Pivotallysecured to the upper end of feed lever 33 is a pawl 37 the end of whichnormally engages the teeth of ratchet28 because of spring 38 secured tosaid pawl and to side plate 14. Rocking of feed lever 33, will cause thepawl 37 to partially rotate the platen and establish the familiar linespacing for the paper, and for this purpose the feed lever 33 isprovided at its upper end with stop faces 39, 40 and 41. A projectinglip 42 at the end of a lever 43 is arranged to be mowed into the path ofthe stop faces, and, contacting therewith will limit the rearwardmovement of the pawl 37 and feed lever 33. As shown clearly in Figure 4,the lever 43 1S plvotally mounted on the side plate 14 at 44, and oneend thereof extends upwardly adjaeentthe side plate 14 and isretained inany desired position by notches 45 of a plate 46 secured to plate 14.From the above it will be o bvious that the stop 39 contacting with hp42 will allow no backward movement of the pawl 37; the stop 40contacting with lip 42 will permit the pawl 37 to move backward a dstance such that on its forward move ment it will rotate the ratchet onetooth.

*Stop 41 will permit the rotation of the ratchet two teeth. Thus meansare prosubstantially triangular in shape.

vided for line spacing the paper, no space,

single space, or double space as desired.

Mounted loosely in the side plates 14 is a shaft 47 which supports thepressure roll frames, each comprising two connected swinging arms 48supporting pressure rolls 49. The pressure rolls are normally held incontact with the platen 18 by means of springs 50, one end of each ofwhich is secured to, the connecting elements for the swinging arms, andthe other ends of each of which are secured to ashaft 51 rigidly securedbetween the side plates 14 at the rear thereof and relatively below theupper ends of the connected arms 48 (see Fig. 7)'.

Loosely mounted between the plates 14 and substantially parallel withthe shaft 51 is a relatively rectangular shaft 52 having pinned to eachend thereof a rock arm 53,

The upper ends of connected arms 48 of the pressure rolls rest againstthis shaft 52 and limit the movement of the pressure rolls. The shaft 52is normally held in elevated position by means of a spring 53', securedto one of the rock arms 53 at 51 at one end and having its other endsecured to the shaft 51 (see Fig. 2). Each rock arm 53 is provided witha stop projection 54 which abuts against a shaft 55 rigidly securedbetween side plates 14 at the uppermost portion thereof.

From an inspection of Figure 7 it will be apparent that upon rocking ofarms 53, the shaft 52 will be rocked forwardly, thus rocking the arms48, supporting the pressure rolls, ontheir pivots and forcing thepressure rolls 48 away from their engagement with the laten.

Secure to and extending between the forward portions of rock arms 53 isa paper release bar 56 having secured thereto an upwardly extending,outwardly curved guide member 57 which is adapted to force paper comingthereagainst forwardly, thus preventing its' becoming entangled with themechanism of the machine. Also secured to said bar 56 by means of pins58 or the like, and arranged in spaced relation to the before mentionedguide member 57 is a saw tooth cutting member 59 (see Figs. 1, 3 and 7).As will be apparent the paper passes between the saw tooth cuttingmember 59 and the guide member 57, the pins 58 serving as guide elementsfor the paper during its passage.

The specific structure of the bar 56 is illustrated in Figures 5 and 6wherein it can be seen that the rear face of bar 56 is pro-- vided withflanges 60 forming a guideway for supporting paper guides 61 havingportions 62 thereof arranged at substantially right angles and seatingslidab-ly in the guideways. The portions 62 of the guides or ears areprovided with slots 63 through core 82 of the pa er roll.

. on the spindle 76 being tensions formed integral and preferably a partof, the arms 66. The hook shaped ends are designated as 72, 73 and 74respectively; 72 being positioned on shaft 20, 7 3 being mounted onshaft 47 and 74 being mounted on shaft 55. As shown in Fig. 2, the lowerends of ,arms 66 are flanged as at 7 4, screws 7 5 securing said arms tocasting 11.

These arms 66 serve as a supporting means for a paper roll and itsspindle as can be clearly seen in Figure 7 in which 75 indicates thepaper roll. Pivot-ally secured to shaft 67 and extending rearwardlythere- .from is a plate 76 which is normally held in elevated positionby means of a spring 77, one end of which is secured to a de ending arm78 of the plate, the other end ing secured to the bar 68, thus providinga brake for the paper roll as will be apparent; The upper portion ofthis late 76 is provided with an extension 7 6 w ich serves as a stopand also a finger grip for said plate, stop adapted in certain positionsto abut against the upper portion of one of the arms 66 before mentioned(see Fig. 2).

Particular attention is directed to the paper roll supporting element orspindle 79 which is clearly illustrated in Figures 8 and 9. The: upperend of one of the arms 66 is provided with an interiorly screw threadedbearing 80 which receives the reduced threaded end of the spindle 79.Adjacent the threaded end of the spindle is an enlargement 81 which isreceived within the Slidably mounted 9 is a collar 83 which is receivedwithin the core 82 of the aper roll. The collar 83 is provided with a.ange 84 adapted to be positioned against the paper on said roll asclearly shown in Figure 8, and secured to said flange 84 and referablyformed integral therewlth is a 100 element, which in reality comprises aflange or collar 85, which latter is provided with a recess 86 in whichis seated the arcuate portion of a 7 spring 87.- The flange 85. oppositethe recess 86 is split, as shown at 88, and the remaining portion 89 ofsprin 87 is straight and bears against the spindle 9 as more clearlyshown in Figure 10,.and is adapted to be positioned within an annularrecess 90. formed in the spindle 7 9.

With adding machines in use at the presspring portion 89 engaging inrecess 91 thus firmly retaining the paper roll in its desired position.

The-opposite arm 66 of the paper supporting means is provided with anopening 92 at the end thereof, and the end of the spindle 7 9 ispositioned therein. The opening 92, it can be seen, is of greaterdiameter than the spindle 79 but is substantially the same diameter asthe enlarged end 93 of the spindle adjacent the knurled button 94secured to the end of the spindle. To replace a paper roll, the button94 is turned thus unscrewing the spindle from the bearing 80. When thereduced end is free the spindle may be tilted as shownin Figure 9, thuspermitting the replacement of a roll as will be ap arent.

As s own in Figure 7, in which the paper is designated as 95, said paperis fed from the roll between guides 62 which may be adjusted toaccommodate the width of the paper used, the pressure rollers 49 and thelaten, and then up betweenthe pins 58, and

tween cutting member 59 and the paper release bar 56, then up in frontof the guide member 57 which forces the paper forwardly and prevents itsentanglement with any of the mechanism. 7

It is believed that the operation of this device will be'apparent fromthe above description, taken in conjunction with the drawings but Idesire it to be understood that the drawings are for illustrativepurposes only and that various changes in the form and proportions ofthe device may be made within the scope of the appended claims withoutdeparting from the spirit of the invention. 4
